What is an exothermic process?
An exothermic change is a change that releases heat. Combustion is an exothermic chemical reaction.Adding water to sulfuric acid releases heat, called exothermic heat of mixing. Exothermic changes are the opposite of endothermic changes that absorb heat when they take place.
Why are changes of state chemical changes?
They aren't; a change of state is a physical change
What happens when you turn solid into liquid into a gass?
These are changes in physical state, which are physical changes.
Classify as chemical and physical change-freezing of water?
Physical. changes of state (solid, liquid, gas) are physical changes.
What kind of changes in substances are always physical changes?
The kinds of changes in substances that are always physical changes are changes in the state. This is the change from solid, to liquid and then to gas and the reverse.
Is exothermic a physical or a chemical change?
It can be either. Some exothermic processes, such as combustion, are chemical changes while others, such as condensation, are physical.
Which state changes are exothermic and endothermic?
freezing is exothermic, melting is endothermic, evaporation is endothermic, condensation is exothermic.

Are state changes chemical or physical changes?
Physical Changes
Are state changes physical or chemical changes?
A change of state: Solid <-> Liquid <-> Gas A change of state is a physical change.
Does changes in a state of matter involve a physical change?
A chaqnge of the state of matter is allways a physical change.
Why are changes of state chemical changes?
They aren't; a change of state is a physical change
When the temperature changes cause of a reaction is it exothermic or endothermic?
It is exothermic
Is melted ice is physical?
physical because its changing state. changes of state mean physical

Is melting ice a physical property?
physical because its changing state. changes of state mean physical
Classify as chemical and physical change-freezing of water?
